Patent DE-2339430-A1 (DE)
Title: Electrical energy source for vehicles independent of engine - utilising kinetic energy expanded in suspension uses linear electric generators as dampers
Inventor: FURUGARD ERIK
IPC: H02K7/18
Filed: 1973-08-03
Abstract: The purpose is to make better use of the fuel burnt in the motor by employing it only for propulsion, gaining the electrical energy required for pumps, fans, lights and other accessories by utilising the inevitable relative motion between parts of the vehicle as it goes over bumps in the road. Both vertical and torsional motion may be employed, either independently or together. The suspension system may be used to carry the parts of linear generators, which can form part of the required damping, so that some at least of the energy dissipated in the damping process is used instead of being wasted as heat.

Title: Heating sub-cooled ammonia - using ammonia-water mixture as heat transfer agent to avoid freezing heater
Inventor: HIRSCHBERG H GUENTHER DR
IPC: C09K5/04
Filed: 1974-01-24
Abstract: A sub cooled liquid (esp liquid NH3) is heated to near its boiling point by means of a heat transfer medium consisting of a mixture of two components, one of high and one of low boiling pts. (esp. an NH3/H2O mixture) which must be non-azeotropic. Two heat exchangers are used. The NH3/H2O mixture of 20-33% NH3 conc. is contained in the lower shell which is heated by steam at a controlled pressure. The ammonia rich vapour rises into the ammonia heater, condensate being returned. NH3 enters the ammonia heater and leaves after flowing through a series of tubes. Esp. used for heating liquid NH3 stored at 1 atm. pressure (-34 degrees C) to 24 degrees C and 10 atm. IF direct steam heating is used, the tendency is for ice to form on the surface and blockage can occur. The use of a secondary heat transfer medium of NH3/H2O acoids this without loss of thermal efficiency.
